Origin

Small ureteric branches arise from the renal artery, just as it enters the kidney at the renal hilum. The ureter emerges from the kidney at the same location.

Course

The ureteric branches pass immediately to the ureter and form an arterial plexus around it.

Branches

Ramifications of the ureteric branches form arterioles and capillaries that supply the tissues of the ureter. These form anastomoses with ureteric branches from the abdominal aorta.

Supplied Structures

Anatomical variation in the arterial supply of the ureter is common. This long structure is supplied segmentally by overlapping arteries from several sources. The superior third of the ureter is supplied by the ureteric branches of the renal artery.

Renal Artery

ScienceDirect image

Dissection of the renal artery refers to a disruption of the intima that extends into the media (Figs. 1.90 and 1.91), with creation of a false lumen or a double channel, or results in a complete vascular occlusion causing renal infarction.
